Answer:
29
Step-by-step explanation:
106=2(x+x+5)
53=2x+5
48=2x
24=x
24+5=29
Answer:
B. 90 degrees counterclockwise
Step-by-step explanation:
Multiply the first equation with (-1)
you should get this
-6r + 3t = -6
6r + 8t = -16
start to eliminate
11t = -22
divide by 11
t = -2
substitute
6r - 3(-2) = 6
6r + 6 = 6
6r = 6 - 6
6r = 0
r=0
The answer is f(x)=x²+2x when evaluated with -3 gives you the value of 3
